Can sparse solver does parallel execution on DSS interface?

On PARDISO interface, the number of processors can be set iniparm[3]. However, I couldn't find how to set this parameteron DSS interface on the manuscript. So I wonder whether sparse solver can do parallel execution on DSS interface or not?

Hello,

The number of processors/threads in MKLis to be set by OMP_NUM_THREADS (or MKL_NUM_THREADS - depends on version) environment variable. Also, PARDISO parameter iparm[3] is not currently used forthis purpose (this inaccuracy in documentation will be fixed in nearest releases). So, PARDISO can do parallel executionindependently of the way it called.

All the best,

Sergey

Dear Sir,

Thank you very much for your help. So I can use the DSS interface at ease.

Best regards,
